Non-Traditional Trademarks: Registering Sound, Color, and Shape in India

Non-traditional trademarks go beyond words and logos. Under India's Trade Marks Act, 1999, any mark capable of graphical representation and capable of distinguishing goods or services qualifies for trademark protection. That includes sounds, colours, product shapes, smells, position marks, and motion marks. Section 2(zb) of the Act defines "trademark" broadly enough to accommodate these unconventional identifiers, and the Trade Marks Rules, 2017 provide the procedural framework for filing them. Yet as of 2026, non-traditional trademark registrations in India remain rare compared to conventional word and device marks. The graphical representation requirement, the high threshold for proving distinctiveness, and limited examiner precedent create real barriers. This guide breaks down each type of non-traditional trademark, what Indian law says, how to file, what it costs, and where the practical difficulties lie.

What Are Non-Traditional Trademarks?

A non-traditional trademark (also called a non-conventional trademark) is any mark that does not fit the standard categories of words, logos, numerals, or device marks but still functions as a badge of origin. When a consumer hears the Intel chime, sees the distinctive red sole of a Louboutin shoe, or recognises the Coca-Cola bottle shape without reading the label, they are responding to non-traditional trademarks.

The legal foundation in India rests on Section 2(zb) of the Trade Marks Act, 1999, which defines a trademark as "a mark capable of being represented graphically and which is capable of distinguishing the goods or services of one person from those of others." The definition does not restrict trademarks to visual marks. It only requires two things: graphical representability and distinctiveness. This broad language is what opens the door to sounds, colours, shapes, smells, and other sensory marks.

The Trade Marks Registry (IP India) accepts applications for non-traditional marks under the same Form TM-A used for conventional filings. However, the representation requirements differ significantly. A word mark just needs the word typed out. A sound mark needs musical notation or an audio file. A shape mark needs 3D views from multiple angles. These additional requirements make the filing process more complex and the examination more rigorous.

Globally, non-traditional trademarks have grown steadily since the 2000s. The US, EU, Australia, and Japan all recognise various types. India is still in the early adoption phase, but the legal framework supports registration, and examiner familiarity is increasing with each new filing.

Legal Framework: The Trade Marks Act, 1999

India's trademark law provides the statutory basis for non-traditional marks through several key provisions. Understanding these sections is essential before filing any unconventional mark.

Section 2(zb): The Definition

Section 2(zb) defines "trade mark" as a mark that includes a device, brand, heading, label, ticket, name, signature, word, letter, numeral, shape of goods, packaging, or combination of colours - or any combination thereof. The phrase "shape of goods, packaging, or combination of colours" explicitly brings 3D marks and colour marks within the definition. The use of "includes" (rather than "means") makes this an inclusive, non-exhaustive list, accommodating sounds, smells, and other marks not specifically listed.

Section 9: Absolute Grounds for Refusal

Section 9 sets the barriers that all trademarks must clear. Section 9(1)(a) refuses marks that are devoid of distinctive character. For non-traditional marks, this is the most common ground of objection because sounds, colours, and shapes often lack inherent distinctiveness. The proviso allows registration if the applicant demonstrates acquired distinctiveness through use before the filing date.

Section 9(3) specifically targets shape marks. It prohibits registration of shapes that: (a) result from the nature of the goods themselves, (b) are necessary to obtain a technical result, or (c) give substantial value to the goods. This three-part test eliminates functional or ornamental shapes from trademark registration. A pill capsule shape fails test (a). A gear tooth profile fails test (b). A decorative vase shape might fail test (c).

Section 11: Relative Grounds for Refusal

Section 11 prevents registration of marks that are identical or confusingly similar to existing marks. For non-traditional marks, this means a sound mark cannot be registered if it is identical to or closely resembles an already registered sound mark in the same class. The similarity assessment for non-traditional marks is more subjective than for word marks, giving examiners wider discretion.

Types of Non-Traditional Trademarks

Non-traditional marks span multiple sensory categories. Each type has different representation requirements, distinctiveness thresholds, and practical challenges. Here is a detailed breakdown.

Sound Marks: Filing, Examples, and Indian Case Law

Sound trademarks are the most successfully registered category of non-traditional marks in India. A sound mark protects a specific audio sequence that consumers associate with a particular brand. The sound can be melodic (a musical tune) or non-melodic (a distinctive noise like a roar or chime).

How to File a Sound Mark in India

The applicant must submit the sound in a format that satisfies the graphical representation requirement. Accepted methods include:

• Musical notation on a standard five-line staff, showing notes, key, time signature, and tempo
• Audio file in MP3 format not exceeding 30 seconds in duration
• A written description of the sound accompanying the notation or audio file

The application is filed on Form TM-A at the IP India portal with the sound type indicated. The government fee is ₹4,500 for startups and individuals or ₹9,000 for other entities when filed electronically.

Notable Sound Marks Registered in India

India has granted sound trademark registrations to several prominent brands. The Yahoo yodel (the distinctive "Ya-hoo!" shout) was among the first sound marks registered in India. ICICI Prudential registered its advertising jingle. The Nokia ringtone (the "Gran Vals" guitar excerpt) secured protection as a sound mark. Britannia Industries registered its four-note chime. These registrations demonstrate that the Indian Registry is receptive to sound marks, provided the representation is clear and the sound is demonstrably distinctive.

Challenges with Sound Marks

Not every sound qualifies. Generic sounds, common musical phrases, and functional audio signals (like a car horn pattern or a microwave beep) lack distinctiveness. The sound must function as an indicator of commercial origin, not merely as a pleasant or informational audio. If your business has used a unique audio signature in advertising for several years and consumers recognise it, that sound likely qualifies. If you composed it last month and have no market recognition, expect an objection under Section 9(1)(a).

Colour Marks: Single Colours and Colour Combinations

Colour trademarks protect a specific colour or colour combination that consumers associate with a particular brand. They are among the most contentious non-traditional marks because colours are a limited resource - granting exclusive rights over a colour can restrict competitors unfairly.

Single Colour Marks

Registering a single colour as a trademark requires an exceptionally high threshold of proof. The applicant must demonstrate that the colour has acquired secondary meaning - meaning consumers in the relevant market associate that specific shade exclusively with the applicant's brand. Cadbury purple (Pantone 2685C) for chocolate, Tiffany blue (Pantone 1837) for jewellery packaging, and Christian Louboutin red for shoe soles are globally cited examples.

In India, single colour mark registrations are extremely rare. The Trade Marks Registry typically raises objections under Section 9(1)(a) (devoid of distinctive character) and requires extensive evidence including sales data spanning at least 5 years, advertising spend, consumer surveys, and declarations from trade bodies. Even with strong evidence, success is not guaranteed.

Colour Combination Marks

Combinations of two or more colours in a defined arrangement face a relatively lower (though still high) threshold. The application must specify each colour using standardised codes (Pantone, RAL, or equivalent), describe the arrangement and proportions, and provide visual representations. Colour combinations used consistently in branding, packaging, or product design for extended periods have a better chance of registration than single colours.

The Acquired Distinctiveness Burden

For any colour mark, the core challenge is proving that the colour functions as a trademark rather than a decorative or aesthetic element. Evidence typically includes:

• Revenue and sales figures for products bearing the colour mark over 5+ years
• Advertising expenditure specifically promoting the colour association
• Consumer survey results showing brand-colour association
• Media articles and trade publications referencing the colour-brand link
• Declarations from distributors, retailers, or industry participants

Shape and 3D Marks: Product Shapes and Packaging

Three-dimensional trademarks protect the shape of goods or their packaging where the shape itself identifies the commercial origin. The Coca-Cola contour bottle, the Toblerone triangular prism, and the Zippo lighter shape are globally recognised 3D marks. In India, Section 2(zb) explicitly includes "shape of goods" within the trademark definition, and Section 9(3) sets the boundaries.

Section 9(3) Exclusions

Not every product shape can be trademarked. Section 9(3) bars registration of three categories of shapes:

• Shapes resulting from the nature of goods: A football must be spherical. That shape cannot be trademarked because it is inherent to the product category.
• Shapes necessary to obtain a technical result: If a product's shape is dictated by its function (e.g., a specific gear tooth profile for mechanical efficiency), it belongs in the patent domain, not trademark law.
• Shapes that give substantial value to goods: If consumers buy the product primarily because of how it looks (aesthetic appeal of the shape itself), the shape adds substantial value and cannot be monopolised through trademark registration.

Indian Case Law on Shape Marks

In Zippo Manufacturing Co. v. Anil Moolchandani, the Delhi High Court upheld the distinctive shape of the Zippo lighter as protectable. The court noted that the shape had acquired secondary meaning through decades of consistent use worldwide and that imitation of the shape amounted to passing off. This case is one of the strongest Indian judicial precedents for 3D trademark protection.

In Colgate Palmolive Co. v. Anchor Health & Beauty Care Pvt. Ltd., the court examined whether the shape and packaging of a toothpaste tube could be protected. The case reinforced that product packaging shapes can qualify for protection where they are distinctive and not purely functional.

Filing Requirements for 3D Marks

The application must include multi-angle views of the shape (front, back, side, top, bottom), a written description specifying which elements are claimed as the trademark, and a statement that the application is for a three-dimensional mark. If possible, include evidence of the shape's market recognition and its association with your brand. The examiner will assess whether the shape clears the Section 9(3) hurdles before evaluating distinctiveness.

Smell Marks: The Most Challenging Category

Olfactory trademarks (smell marks) represent the frontier of non-traditional trademark law. The idea is straightforward: if a specific scent is so closely associated with a brand that consumers identify the source by smell alone, that scent should be protectable. The reality, however, is far more complicated.

The Global Landscape

The most cited smell mark case is Vennootschap onder Firma Senta Aromatic Marketing's "scent of fresh cut grass" for tennis balls, registered by the EU's trademark office (then OHIM) in 1999. However, the European Court of Justice later set a stricter standard in the Sieckmann case (2002), ruling that a chemical formula or written description alone does not satisfy graphical representation. This effectively closed the door on most smell mark applications in the EU. The US Patent and Trademark Office has been slightly more permissive, granting a few olfactory marks including a plumeria scent for sewing thread.

Why Smell Marks Cannot Be Registered in India (Yet)

India's graphical representation requirement under Section 2(zb) is the primary obstacle. How do you graphically represent a smell? A written description like "the scent of vanilla" is not precise enough - vanilla scents vary widely. A chemical formula describes a compound, not the subjective olfactory experience. No technology currently exists that can "print" a smell onto a trademark application with the same precision that musical notation captures a sound or Pantone codes capture a colour.

Until India amends the graphical representation requirement (as the EU did in 2017 with its shift to "representation in a clear, precise manner") or until scent-capture technology evolves, smell marks remain theoretically possible but practically unregistrable in India. As of 2026, zero olfactory marks have been registered by the Indian Trade Marks Registry.

What Business Owners Should Know

If your product has a distinctive, non-functional scent that you use as a brand identifier, document everything - the formulation, marketing materials referencing the scent, consumer feedback, and any advertising that promotes the scent as a brand attribute. If India relaxes the graphical representation standard in the future, you will want that evidence ready. In the meantime, trade secret protection and passing off claims remain the primary legal tools for protecting distinctive scents.

Position Marks and Motion Marks

Two less-discussed categories of non-traditional trademarks are position marks and motion marks. Both are recognised in international trademark practice and can be filed in India under the broad Section 2(zb) definition.

Position Marks

A position mark protects the specific placement of an element on a product. The mark is not the element itself (which might be a colour, pattern, or device) but its consistent location on the goods. The most famous example is Christian Louboutin's red sole, which is a colour applied to a specific position (the outsole of a high-heeled shoe). Adidas's three stripes in a specific position on footwear is another global example.

In India, filing a position mark requires a clear image showing the product with the mark in its claimed position. The non-claimed parts of the product are typically shown in dotted lines, and the claimed element is shown in solid lines. A written description must explain that protection is sought not for the element in isolation but for its placement on the product. The examiner will assess whether the positioning itself is distinctive or merely ornamental.

Motion Marks

A motion mark (or multimedia mark) protects a moving image sequence that functions as a trademark. The Columbia Pictures lady with the torch (the animated sequence before films), the Lamborghini door opening vertically (the scissor-door motion), and animated logos used in digital advertising are examples. With brands increasingly deploying animated identities across apps, websites, and video platforms, motion marks are gaining commercial relevance in 2026.

Filing in India requires a series of sequential still frames that capture the key stages of the motion, accompanied by a detailed written description of the movement. Alternatively, a video file can be submitted. The challenge is proving that the motion itself, not just the static visual elements, is distinctive and serves as a source identifier.

Practical Relevance for Indian Businesses

Position and motion marks are most relevant for businesses in fashion, luxury goods, consumer electronics, entertainment, and digital services. If your brand consistently places a visual element in a specific position on your product (and consumers recognise that placement), or if your brand uses a distinctive animated sequence, consider filing. The costs are the same as any trademark application, and the protection can be commercially significant in preventing copycat designs.

Registration Process and Difficulty Comparison

The filing procedure for non-traditional marks follows the same broad steps as conventional trademarks, but with additional representation requirements at each stage.

Step 1: Trademark Search

Before filing, conduct a search on the IP India portal to ensure no identical or confusingly similar mark exists in your class. For sound marks, this involves searching for similar melodies. For shape marks, it means reviewing 3D marks in the same product category. Given the limited number of non-traditional registrations in India, the search is often less crowded than for word marks.

Step 2: Prepare the Application

File Form TM-A with the following based on your mark type:

Step 3: Examination

The Trade Marks Registry examines the application for compliance with Sections 9 and 11. Non-traditional marks face a higher scrutiny threshold. Expect an examination report raising objections about distinctiveness (Section 9(1)(a)), graphical representation adequacy, or shape exclusions (Section 9(3)). You must respond within 30 days (extendable by another 30 days) with arguments and evidence.

Step 4: Publication and Opposition

If accepted, the mark is published in the Trade Marks Journal for 4 months. Any third party can file an opposition during this period. For non-traditional marks, oppositions are more common because competitors may argue that granting exclusivity over a colour, shape, or sound would unfairly restrict the market.

Step 5: Registration

If no opposition is filed (or if the opposition is decided in the applicant's favour), the mark proceeds to registration. A registered trademark is valid for 10 years from the filing date and can be renewed indefinitely in 10-year periods through trademark renewal. The renewal fee is ₹5,000 (individuals/startups) or ₹10,000 (others) filed on Form TM-R.

Registration Difficulty by Mark Type

Not all non-traditional trademarks are equally difficult to register. Here is a practical comparison based on Indian registry practice and global trends as of 2026.

Indian Case Law and Judicial Precedents

While Indian case law on non-traditional trademarks is still developing, several judicial decisions provide guidance on how courts approach these marks.

Zippo Manufacturing Co. v. Anil Moolchandani (Delhi High Court)

This is one of the most significant Indian cases for 3D/shape mark protection. The Delhi High Court recognised that the distinctive shape of the Zippo lighter had acquired secondary meaning through decades of worldwide use. The court granted an injunction against the defendant for manufacturing lighters that copied the Zippo shape, holding that the imitation constituted passing off. The case established that product shapes with demonstrated consumer recognition are enforceable in India, even without formal trademark registration, under the common law doctrine of passing off.

Colgate Palmolive Co. v. Anchor Health & Beauty Care Pvt. Ltd.

This case examined trade dress and packaging shape protection. The court analysed whether the overall shape, colour scheme, and layout of Colgate's toothpaste packaging had achieved distinctiveness. The ruling reinforced that the overall commercial impression created by product packaging can be protected, and that competitors who imitate the entire trade dress (including shape, colour arrangement, and layout) risk passing off liability.

Cadbury UK Ltd. and the Purple Colour Dispute

While the primary litigation occurred in the UK, Cadbury's efforts to protect Pantone 2685C (Cadbury purple) as a single-colour trademark have influenced Indian discourse. The UK courts ultimately denied broad protection for the colour in its entirety, but the case demonstrated the evidentiary standard required: decades of exclusive use, billions in sales, and overwhelming consumer association. Indian applicants seeking single-colour protection should treat the Cadbury standard as the practical minimum for evidence preparation.

Yahoo Inc. Sound Mark Registration

Yahoo's registration of the "Yahoo!" yodel as a sound mark in India was a landmark event. It demonstrated that the Indian Trade Marks Registry would accept and process sound mark applications where the graphical representation (musical notation) was clear and the sound was demonstrably distinctive. This registration opened the path for subsequent sound mark filings by ICICI Prudential, Britannia, Nokia, and other brands.

Global Comparison and the Future of Non-Traditional Trademarks in India

India is not alone in grappling with non-traditional trademarks. Here is how major trademark jurisdictions compare.

The trend globally is toward relaxing strict graphical representation requirements in favour of "representation by any appropriate means." The EU's 2017 reform was a watershed moment, allowing sound files, video clips, and digital colour samples as valid representations. India has not yet undertaken a similar statutory amendment, but the Trade Marks Rules, 2017 already accept MP3 files for sound marks, suggesting incremental adaptation.

Costs, Timelines, and Practical Tips for 2026

Here is what you should budget and plan for if you are pursuing a non-traditional trademark registration in India.

Government Fees

The official fee for filing Form TM-A electronically is ₹4,500 per class for individuals, startups (DPIIT-recognised), and small enterprises. For all other entities (companies, LLPs, large enterprises), the fee is ₹9,000 per class. These fees are the same regardless of whether you are filing a word mark, device mark, sound mark, or 3D mark. Filing for multiple classes requires separate fee payments per class.

Professional Costs

Non-traditional marks typically require higher professional fees due to the complexity of representation preparation. Expect to pay:

• Sound mark: ₹10,000-₹20,000 for musical transcription, audio preparation, and application drafting
• Colour mark: ₹15,000-₹30,000 including evidence compilation for acquired distinctiveness
• Shape/3D mark: ₹15,000-₹25,000 for multi-angle photography, CAD renderings, and Section 9(3) analysis
• Position or motion mark: ₹10,000-₹25,000 depending on complexity of representation

Timeline Expectations

A straightforward non-traditional trademark application with no objections or oppositions takes 12 to 18 months from filing to registration. If an examination report is issued (which is likely for non-traditional marks), add 3 to 6 months for the hearing and response process. Opposed applications can take 3 to 5 years. Budget your IP strategy accordingly - file early.

Practical Tips

• File your conventional marks first. Secure word and logo protection before investing in non-traditional marks.
• Start documenting use immediately. Every advertisement, product launch, and consumer interaction that features your non-traditional mark is potential evidence.
• Use consistent representation. If your colour is Pantone 2685C, use it consistently across all materials. Variation weakens the distinctiveness argument.
• Engage a specialist. Non-traditional trademark filings are not DIY territory. The representation requirements and evidence standards demand professional expertise.
• Consider international filing. If you operate globally, the Madrid Protocol allows you to extend your Indian registration to 130+ countries through a single application filed via the IP India office.

What the Future Holds for India

Non-traditional trademark protection in India is at an inflection point. Several developments suggest that the next few years will bring meaningful expansion in both filings and registrations.

The Trade Marks Rules, 2017 already accommodate some non-traditional representations (MP3 for sounds, multi-angle views for 3D marks), even though the Act itself has not been formally amended to drop the graphical representation requirement. This suggests a pragmatic approach by the Registry: adapt the rules while waiting for statutory reform. If India follows the EU's trajectory, a formal amendment replacing "graphical representation" with "representation in a clear, precise, self-contained, easily accessible, intelligible, durable, and objective manner" could come within the next decade.

Digital-first branding is accelerating the commercial importance of non-traditional marks. App sounds, animated logos, interactive colour schemes, and product design languages are now central to brand identity. As Indian startups and companies invest more in these brand elements, the demand for legal protection will push the Registry and courts to develop clearer standards. Would a distinctive app notification sound qualify? Almost certainly, under the current framework. What about the haptic feedback pattern of a smartwatch? That is a question Indian trademark law will need to answer soon.

For business owners in 2026, the practical advice is clear: build the evidence trail now. Document your use of non-traditional brand elements consistently. Invest in conventional trademark protection as your foundation. And when your non-traditional mark has accumulated sufficient distinctiveness, file. The legal framework supports it. The Registry is receptive. And the first movers will have the strongest positions.
